“…Researchers around the world have been carrying out studies for reducing the CO 2 concentration in the atmosphere (Alpert and Maulbetsch, 1996;Audus and Oonk, 1997;Fujii, 2001). One of the effective countermeasures for the aforementioned problem is CO 2 fixation, in which useful ions in waste brine after sodium chloride is removed from seawater, such as Ca 2+ , Mg 2+ , and Li + , are recovered as carbonates by reactive crystallization with exhaust CO 2 gas (Tsuge et al, 2002).…”

In this study, we used minute gas-liquid interfaces around CO 2 microbubbles activated by microwave irradiation as new reaction fields and developed a crystallization technique to produce lithium carbonate (Li 2 CO 3 ) nanoparticles. At the minute gas-liquid interfaces, nucleation occurs predominantly because of the formation of numerous local supersaturation regions at higher temperatures; hence, fine-sized Li 2 CO 3 particles with a narrow size distribution are crystallized, as the Li 2 CO 3 solubility decreases sharply with an increase in temperature. Microwaves (2.45 GHz) were used to irradiate an aqueous solution containing lithium ions and CO 2 microbubbles in a waveguide-type microwave apparatus. The heating method, rate of temperature increase (r T r T r T ) and average bubble size (d bbl d bbl d bbl ) were considered as the operation parameters and varied; the combined effects of CO 2 microbubble formation and microwave irradiation on the reactive crystallization of Li 2 CO 3 nanoparticles were examined. Consequently, during microwave irradiation of the solution containing CO 2 microbubbles, the crystallization of Li 2 CO 3 nanoparticles was significantly accelerated with an increase in r T r T r T and a decrease in

CO2 utilization involves many disciplines -fields as different as apples and oranges. Technology assessment is a common tool for evaluation. This article analyses its current state in CO2 utilization. First the steps of chemical product development are matched with Technology Readiness Levels for classification. Second, relevant literature is selected and assessment methods, and indicators are examined. The analysis shows that standardization in CO2 utilization technology assessment is low. Current research addresses some but not all assessment fields and tends to use a large range of indicators, making comparison difficult. Overall standard methods are needed, as they could facilitate technology comparison and provide a better understanding of tradeoffs. Future assessments should be extended by the definition of a standard set of assessment indicators, the further adoption of social impact assessment for all TRL and the inclusion of environmental impact assessment at early stages.

“…To evaluate the contribution of the process to the CO 2 balance, some shortcut methods have already been published. Especially, the above‐mentioned procedure 9 is advisable in this context. As a further criterion to those suggested by Audus and Oonk 9, we recommend a comparison of the amounts of solvent used in the conventional and CCU processes, since high amounts of solvents cause high efforts in product separation.…”

“…This aspect is so far the most discussed one in the literature, since process evaluation is a topic not only in the context of CCU technologies. An assessment procedure especially for CCU processes has been proposed by Audus and Oonk 9. For a quick estimation, they suggest a comparison of the new process to the conventional process for the same product by looking at some simple criteria.…”

Chemical utilization of carbon dioxide seems to be an attractive option for the mitigation of greenhouse gas emissions. However, the respective processes themselves cause substantial greenhouse gas emissions. To achieve a good CO 2 balance, it is necessary not only to fix carbon but also to do this efficiently in terms of reactant supply and energy demand. An evaluation of the CO 2 balance requires detailed process simulation for the utilization reaction and the supply chain. To allow a quick evaluation of the potential to mitigate emissions, a number of estimation methods are presented.
